BRUSH FOB CLEARING THE NGIL FRQM THE COMB CIRCLES OF GOMBING MACHINES.

Application filed July 1, 1925, Serial. No. 40,818, and in Great Britain April 27, 1925.

This invention relates to improvements connected with what are known as clearer brushes used in connection with the circles of wool combing machines. The present brushes are circular in shape with annular bristling, and revolve by frictional contact with the comb circle, and to this end are mounted in holders which in turn are mounted on the machine frame, adjustment being provided to allow for decreasing length of bristle.

My invention is in the nature of a brush carrying a shaft adapted to engage a suitable holder which holder is pivoted or tilt able to permit of the removal and replacement of the brush without dismounting the holder, a rest, stay or locating piece for the holder is also provided.

The nature and operation of my invention are fully disclosed in the following specification, and accompanying drawings in which similar reference letters indicatecorresponding parts.

Fig. 1 is a side elevation with the brush holder in section.

Fig. 2' is a rear elevation.

Fig. 3 is a plan of the brush holder stay referred to and Fig. l is a plan of the lower bracket which supports the device adjustably fromthe machine frame.

The brush B is of any usual form adapted to fit a holder H, and to provide ease of removal and insertion of the brush from or into its holder. 1 provide the brush with a plain central stem or shaft 13. The holder H in the preferred form has a long internal bearing H leading to a recess H in which is seated a ball thrust member 0 pressed towards the brush end by a spring C which for fitting purposes is retained by a screwed member C having means to assist in its tightening and removal such as indents C Fig. 2. This form of holder has for its purpose obvious advantages in that the brush is readily removable, and after setting in relation to the comb circle (not shewn in the drawings) has a yielding action and will also revolve freely under frictional contact with the comb circle. In order to be able to quickly remove or replace a brush B the holder H is made tiltable, and to this end arms or brackets P on the holder carry a pivot pin P which passes through a b ng o c ss piece D at a adjustable shaft D:

By merely pivoting the holder, unless a stop or stops was provided the holder could not be retained at its correct angle in relation to the comb circle, therefore it is necessary to provide a suitable stop arrangement which is adjustable, and to this end on the shaft D I mounta boss F carrying an arm F which extends towards and under the nose of the holder H as in Fig. 1. If the angle of the holder requires to be al.- tered the arm F is raised or lowered on the shaft D and clamped thereto by suitable means such as the screw F in the boss F. The shaft D is seater in the boss G of the base piece G which is bolted in the desired position to a suitable part of the machine frame, substantially in the manner now common to noil brush supports. The base piece G has a boss G and securing screw G2.

By means of the apparatus substantially as before described the brush may be moved nearer to or away from the comb circle. It may be raised and lowered or altered as to angular contact, and when it is desired to remove or replace a brush the holder may be moved upwards in the direction of the arrow in Fig. 1, all without dismounting the apparatus in any way.

The stay arm F is in no way altered, and to return the brush to its correct position it is only necessary to return the holder against the stay arm F.

It will be found that an apparatus of this description ensures even wear on the bristling; of the brush, and such bristling may be used almost to the brush stock.

What I claim is 1. A combing-machine brush, comprising a supporting; member, a brush holder pivoted to said member for angular move ment in a vertical plane, and a brush having a stem mounted for rotation in said holder.

2. A noil brush holder for brushes for clearing noil from the comb circles of combing machines pivotally mounted on a support and provided with a stay arm for ensuring the correct return of the holder.

A combingonachine brush, comprising a supporting member, a brush holder pivoted to said member for angular movement in a vertical plane, a brush having a stem mounted for rotation in said holder, and a. springpressed ball carried by the brush holder ongaging the end of said stem and exerting pressure thereon tending to eject the stem, from the holder i. A. noil brush holder for brushes for clearing noil from the comb circles of combing machines, pivotally mounted on an ad jnstable support, said adjustable support carrying and. adjustable stay piece or stop for the holder to enge e in the Working poltion.

A noil brush, a pivoted brush holder, an

adjustable stay and adjustable supporting member for the pivot carried from an ad- 10 justable base bracket whereby the brush and its holder may be adjusted required.

In testimony whereof I have signed my name to this specification.
